SIGNALING SYSTEM AND APPARATUS.

Specification of Letters Patent.

Patented June 30, 1914.

Application filed June 11, 1913. Serial No. 773,063.

To alZ whom it m flfl/ concern Be it known that I, CLARENCE E. BEACH, of Binghamton, Broome county, State of New York, have invented new and useful Improvements in Signaling Systems and Apparatus, of which the following is a spec1- fication.

My invention relates to signaling systems, and concerns particularly the construction and operation of signaling units, whereby units such as fire alarm boxes on street corners, may be caused to be set in operation from remote points.

lvlore particularly the invention involves a simplified arrangement in signaling or alarm boxes, and an improved circuit arrangement whereby auxiliary alarm or signaling circuits can be controlled from remote points to cause the box to be set in operation to send in signals or alarms.

My invention is particularly adaptable to the fire alarm field, where fire alarm boxes are placed at street corners and auxiliary alarm circuits, installed in buildings, are to be connected with such boxes to control the tripping thereof. In prior systems of this class, complicated mechanism has been attached to the fire alarm boxes for taking care of the auxiliary control, such additional apparatus usually involving electro-1n ag-. netic mechanism and leverage mechanism connecting with the alarm box parts, and also extraneous setting mechanism. The circuits for such prior systems also require 'sepa ate current sources and no provision is made so that fire alarm officials or inspectors can ascertain the condition of the auxiliary system by looking at the box.. In general, said prior systems are very complicated and not always reliable.

Among the important objects of my invention are to provide such arrangement for accommodating auxiliary remote control circuits that all controlling mechanism for such circuits can be placed within the alarm movement case as an intimate part of the mechanism therein; to provide such arrangement that extra electromagnetic mechanism and current source for the auxiliary system can be entirely dispensed with; to provide such arrangement that the'auxiliary circuit forms merely an adjusting and controlling circuit for the signaling box magnet; to provide an arrangement whereby the current control for the non-interference electromagnet by the auxiliary circuit is accomplished by a minimum number of simple lever mechanisms applied. to the main box mechanism asan intimate part thereof; to provide such arrangement that a mere inspection of the main signaling box from the exterior thereof will indicate the condition of the auxiliary system and whether or not such system is set for operative control of the box; to provide a system of auxiliary control which is not confined for use in connection with one style of signal box but which can be applied to other existing styles of boxes; and in general, to provide a more simplified arrangement in fire alarm boxes which will enable the box to be accurately and efficiently controlled from remote points without the use of expensive and complicated extraneous mechanism, such as has been heretofore resorted to.

In the accompanying drawings in which I have illustrated the application and operation of my invention Figure 1 is a front elevational view of a firealarm box signaling mechanism showing the auxiliary circuit controlling mechanism applied, and in the not set position, Fig. 2'is a top view, Figs. 3 and 4 are sectional views on lines 3 and 4: respectively of Fig. 1 showing auxiliary circuit controlling switch mechanism, Fig. 5 is a front elevational view of the various inclosing casings, Fig. 6 is a horizontal sectional view showing the casing arrangement,

and Fig. 7 is an elevation of a detail of the mechanism;

In the drawings, the magnet 10 has the armature structure 11 pivoted at 12 and connected at its upper end with a spring 13 which tends to keep the structure in retracted position. The end-14 of the downwardly extending arm 15 in the armature structure cooperates with signal wheel 16 mounted on the shaft 17 of the signaling train designated as a whole by S, this train being driven by spring power, not shown, but which is readily understood in the art. The teeth t of the signal wheel and the notches between the teeth control the operation of the signaling contact 18, which cooperates with another signaling contact 19 to control the signaling circuit. At its periphery the signalwheel carries a lateral flange; 20 which is broken in correspondence with the breaks between the teeth and which, at times, serves to lock the armature structure iii attracted position and to release the armature structure when its end 14: is opposite the notches between the teeth, this operation being also understood in the art. An L shaped arm 21 is pivoted at 22, and pivoted at an intermediate point to the upper end of this arm is the detent lever 23, whose one end cooperates with the pin 24 on the armature structure and whose other end cooperates with the extension 25 on the escapement pallet 26 associated with the signaling train. The right end of the arm 21 has upper and lower abutment steps 27 and 28 which cooperate with a pin 29 extending from a wheel 30 on shaft 17, a spring 31 engaging with the left end of the arm 21 tending to swing the arm in a counter-clockwise direction. When not set, the parts are in the position as shown in Fig. 1, the pin 29 engaging the sloping left hand side of the abutment on arm 21 near the top step 27 so that the right end of the arm 21 is held down to allow the right end of the detent lever 23 to assume stop engagement with the pallet extention 25 when the armature structure is retracted. The contact block 32 carries two main circuit terminals, 33 and 34:. The terminal 33 carries a contact extension 35 and the terminal 3st carries a contact extension 36, and these contact extensions cooperate to open and close a box shunt, as. will be described later. The left end of arm 21 carries a contact 37 which is adapted to engage with contact extension 36 to disconnect said contact extension from the contact extension 35 and to close a shunt around the signaling contacts, as will be described later, the arrangement being such that when contacts 37 and 36 are in engagement, the signaling circuit contacts 18 and 19 will be shunted and the box shunt opened, and when contact 37 is moved away from contact 36, both the noninterference magnet and the circuit contacts will be shunted; that is, the main line terminals 33 and 31 will be shunted. Pivoted at its right end is a main locking lever 38 whose left end carries a shunting bar 39 adapted for engagement with the main line contacts 33 and 3 1 to short-circuit the main line, This locking lever also carries a pawl abutment 40, which, when the lever is down, is in the path of the abutment pin 41 on the large gear wheel 30 of the train. "When not set, the main locking lever is down, to effect direct connection through bar 39 between the main line terminals, and the pin 41 abuts against pawl 49 so that the train is locked. A main pull} lever 42 is suitably pivoted with its inner end extending below the locking lever 38 so that when the other end of the pull lever is depressed the locking lever will be raised to remove the main line shunt and to allow the train to operate, provided the electro-magnet is energized upon such pulling of the box. A pin is so located on the locking lever that when the lever is lifted to release the train the step 76 of arm 77 may be drawn by the spring 78 under the pin to hold the lever 33 1 up so as to keep the main shunt open.

Upon attraction of the armature, the pin 2-1- will engage the detent lever to swing the right end thereof away from the palletextension so that the train can operate. After the train begins to operate, and so long as the upper step 27 is associated with pin 29, the detent lever will remain in the field of the pallet, but as soon as pin 29 leaves this upper step, the arm 21 can swing in counterclockwise direction to carry the lower step 28 into engagement with pin 29 and to raise the detent lever so that it. can no longer cooperate with the pallet extension. The cooperation of pin 29 with the upper and lower steps of arm 21 is during the period when the end. A of the armature structure cooperates with that section of the flange 20 in advance of the first notch of the signal wheel, and substantially at the time the pin leaves the lower step 23 on arm 21, the

end 1 1 of the armature structure will arrive at the first notch, and the arm 21 can then swing further upwardly. Thus, during engagement of pin 29 with the upper step 27, the armature structure controls the pallet mechanism so that attraction of the armatiu'e will swing the detent lever away from the pallet mechanism, to allow the train to operate, and retraction of the armature structure will allow spring 23 to restore the detent lever to stop the pallet mechanism and the train; and when pin 29 reaches the lower step 28 of the arm 21, the armature is no longer in control of the running train. The armature structure 11 has also an extension 43 for cooperating with the contact 36. The end 14 of the armature structure is normally above the flange 20, and the armature can be attracted sufiiciently to release the train, but not sufficiently to carry extension 4E3 against con tact 36. Pin 29 normally engages with arm 21 to cause contact 37 thereof to engage contact 36 to close the shunt about the signaling contacts 18 and 19, and such shunt is main tained after the is pulled and during the entire engagement of the pin 29 with the upper step 27 or during the time that the armature has control of the pallet mechanism. Such engagement of the contacts 37 and 36 is also maintained during the time that the pin 29 engages with the lower step 28 and it is not until pin 29 leaves this lower step that the arm 21 can swing sufiiciently to break the shunt about the signaling circuit contacts, and when this is efiected, the signal circuit contacts will have closed, and thus be ready to break the signal circuit for the first time. At this time also the end of the armature structure is in association the armature structure is in full control and can be fully attracted to hold the box shunt contacts 36 and 35 open, or to retract upon opening ofthe line at other boxes to close the box shunt and thus prevent interference.

Coming now to the improvements and arrangements for allowing control of the box from remote points, auxiliary setting mechanism is provided for actuating the locking lever 38 to unlock the box and to allow op eration thereof when the non-interference magnet is energized. The pivot shaft 38 to which the locking lever is secured, has, at its outer end, a crank arm 44 secured thereto, and provided with a crank pin 44. On a shaft 45, extending forwardly from the box mechanism supporting frame, is pivoted a hub 46 to which is secured a substantially vertically extending lever 47 whose upper end is adapted to act against crank pin 44 to effect swing of the crank arm and of the locking lever 38. Extending horizontally and toward the left from the hub and having preferably detachable connection therewith, is a setting arm 49, which, when raised, will turn the hub 46 and swing the upper end of the lever 47 to thereby effect raising of the locking lever 38. A spring 50 connected between the upper end of the lever 47 and any stationary frame part tends to resist the setting movement of the setting mechanism and to restore the setting mechanism to normal position when released. Pivoted at an intermediate point adjacent to the setting mechanism, is a detent lever 51 whose left end 51 is overbalanced or provided with spring control which will cause the end 51 to engage in front of pin 48 extending from the upper end of lever 47 after the setting arm 49 has been raised. so as to lock the setting arm and lever 47 in set positio against the power of the spring 50. It should be noted that the pin '75 should lock the arm 38 on step 76 simultaneously with or not later than the locking of pin 48 by detent lever 51. A tongue 52 on lever 51 extends downwardly into the path of the inner end of the main pull lever 42, so that when the box is pulled in the ordinary manner, the detent 51 will be swung to release the pin 48 to allow the setting mechanism to return to unset position. The inner end 51 of this detent lever also projects into the path of pin 53 on the signal wheel 16 of the box train, this pin being so situated that at the beginning of a round of the signal wheel the detent lever will be swung to trip the auxiliary setting mechanism. the purpose of such tripping be ing described later.

The lower end of lever 47 carries a block 54 of insulating material, through which extend upper and lower switch bars 55 and 56. Adjacent the lower end of lever 47 is a block 57 of insulating material mounting upper contact springs 58 and 59 and lower contact springs 60 and 61. The upper contact springs are sutliciently long toengage with the opposite ends of switch bar 55 when the auxiliary setting mechanism is unset, and to become disconnected from the bar whenthe auxiliary mechanism is set. The lower contact springs are shorter so as to be away from the lower switch bar 56 when the auxiliary mechanism is unset and to come into electrical engagement with the op posite ends of the bar when the mechanism is set.

The main line conductors L, L, connect respectively with the contacts 33 and 34 so that when the locking lever 38 is down, its contact bar 39 will short-circuit the main line and bridge out all the box mechanism. The main contact 34 connects through conductor 63 with signaling contact 19 and the signaling contact 18 connects through conductor 64 with one terminal of the winding of the non-interference electro-magnet 10, the other terminal of this winding connecting through conductor 65 with the main contact 33. Contact 37 on arm 21 connects through conductor 66 with contact 18. One limb a of the auxiliary circuit A. connects with spring 60 of the auxiliary mechanism, spring 61 of this mechanism connecting through conductor 67 with the main terminal 33. This spring 61 also connects through conductor 68 with spring 58, and spring 59 connects through conductor 69 with that terminal of the electro-magnet winding which is connected to main contact 33. The other limb a of the auxiliary circuit A connects with main contact 34. The limbs a and a are, of course, normally connected together through any number of switch devices 8 which enable this circuit to be opened at various points. It the auxiliary circuit A is to be connected for service, the setting arm 49 is raised to a set position and is then locked in set position by the pin 48 and detent lever 51. When thus set, the box is ready for operation as soon as the electromagnet can become energized. This electromagnet is connected serially with the main line as follows: from main contact 33 to conductor 65, electro-magnet winding, conductor 66, contact 37, contact 36 and main contact 34. However, when setting has been accomplished, the auxiliary line A will ofier a short circut path around the electro-magnet winding so that even though the box has been unlocked, it cannot operate, as the electro-magnet cannot receive sufiicient current flow to control the train locking detent 23. This short circuit is as follows: from the main contact 33 to conductor 67 spring 61, switch bar 56, spring 60, through limbs o and a of the auxiliary circuit and to the main contact 34. Substantially the entire main line current will, therefore, flow through the auxiliary circuit and the electro-magnet remains deiinergized. If the main electro-magnet winding is of low resistance, it will be advisable to include a resistance R in series with the winding. This resistance is shown in the conductor (35, and forces practically all the current to How through the short circuit A. The mechanical relation of main shunt 33-39-84l and auxiliary shunt A is preferably such that the operation of setting will close the auxiliary shunt at 5661 before the main shunt is broken at 3339-3 l to avoid energizing the electro-magnet 10. If, now, an alarm is to be sent in from any station on the auxiliary circuit, one of the switch mechanisn'is s is actuated to open the short circuit, and upon such opening the electromagnet 10 immediately receives sufficient current flow to attract its armature and the signaling train is released and the box will send in the alarm, provided, of course, that the line is in proper condition to receive the signals. Immediately upon starting of the box, the pin 53 on the signal wheel will engage the detent lever 51 to trip the setting mechanism as before described, and the lower end of lever a? will swing outwardly to connect contact springs 58 and 59 through bar 55 and to disconnect bar 56 from the contact springs 60 and 61. The auxiliary circuit is then positively opened by the disengagement of the springs 60 and 61, but engagement of springs 58 and 59 through bar 55 will close a short circuit around the resistance it, and this short circuit includes conductor 39, spring 59, bar 55, spring 58, ciimductor 5S and conductor 67. The non-interference electro-magnet is thus restored to its normal condition to control the running of the box and to prevent interference. After such signaling operation of the box and after the auxiliary circuit has been closed outside of the box, the setting mechanism is again restored to set position and the auxiliary circuit in then finally closed in the box by the bar 56 and contacts 60 and 61.

it is very important that the setting mechanism be tripped to positively open the auxiliary circuit at contacts 60 and 61 before the box signaling contracts become effective to send in signals, as otherwise the auxiliary circuit could be accidentally closed at re 7 mote points and the non-interference electromagnet rendered inoperative and its armature structure released to shunt out the box during a signal. The pin 53 on the signaling mechanism is therefore so set with reference to the tripping lever 51 that the setting mechanism will be tripped and the auxiliary circuit positively opened and kept open at contacts 60 and 61 within the box before the signaling cont-acts become effective. The assoeiation of the above described setting or circuit controlling mechanism for the auxiliary circuit will not interfere with the normal pulling and operation of the box, for as soon as pull lever 42 of the box is actuated, the tripping lever 51 is simultaneously moved to trip the setting mechanism so that the auxiliary circuit is positively opened when the box starts and is kept open during the entire operation of the box, independently of the condition of the auxiliary circuit. Of course, after a box has been operated either directly or by means of the auxiliary circuit, the setting mechanism will have to be re-set to restore control of the box to the auxiliary circuit.

In order to determine whether or not a box is set for auxiliary circuit control, provision is made so that the setting mechanism or part thereof is visible from the exterior of the housing containing the box mechanism. The box mechanism, including the auxiliary circuit controlling parts, is installed in an inner case i and this case is installed within a middle box m which is locked to the public, and this middle box is inclosed in an outer box 0 which is secured to a pole or other support. As shown in Figs. 5 and 6, the door of the middle box has a hole through which the pull lever L2 projects a suihcient distance to be pulled when the door of the outer box is open. The door of the middle box has also a sight opening 71, through which part of the setting mechanism is visible. As shown, the end of setting arm 49 carries a target 72 having legends thereon, and visible through the sight opening 71 to indicate the condition of the setting mechanism. As shown, the legend Not set appears at the top of the target, and the legend Aux. set appears at the lower part of the target, the upper leg end appearing in front of the sight opening 71 when the mechanism is not setfor auxiliary control and the lower legend appearing in front of the sight opening 71 when the mechanism is set for auxiliary control. Preferably, the sight opening is covered at the rear by a glass plate 73 so as to prevent tampering with the setting mechanism. Thus, the position of the setting arm and, therefore, the condition of the auxiliary circuit can be readily determined without opening the middle box, and the box mechanism can be locked against tampering by unauthorized persons. Instead of having words on the target, the upper part thereof may be of one color and the lower part of another color, to indicate the condition of the auxiliary system, and a sight opening 74 could also be provided in the cover of the outer box so that inspection of all boxes in a line could be quickly made and the condition of the auxiliary circuits quickly determined without the necessity of opening any doors.

It is apparent that, by means of-my invention, an ordinary fire alarm box can, by the addition of a few simple elements, be adapted for auxiliary control from remote stations, and all this can be accomplished without the addition of electro-magnetic mechanisms or complicated circuit controlling mechanisms and without the need of special current sources for the auxiliary circuit, the auxiliary circuit in my improved system being merely in the nature of a shunt or short circuit path around the winding of the noninterference magnet of the box. This auxiliary controlling circuit therefore is under constant test for its continuity while the box is set, and can be readily tested from the central station for grounds, etc. As soon as starting of the box has been effected by the operation of the auxiliary circuit, this circuit is positively and automatically disconnected by the box itself, so that the box may carry out its normal operations of sending in its signal. Also, when the box is directly pulled, the auxiliary circuit or circuits emanating therefrom are automatically and positively disconnected so as not to interfere with the normal operation of the box. Furthermore, the condition of the setting mecha nism and hence of the auxiliary circuit is visible and readily determined without the necessity of opening the various inclosing doors.

As above stated, my invention can be applied to may kinds of boxes now in use, and any modifications in the construction and arrangement of the setting mechanism within said box would come within the broad scope of my invention. Furthermore, changes and modifications can be made in the particular setting and controlling mechanism shown without departing from the scope of the invention.
